Application filed August 30, 190,2. lSerial No. 121,683. (No model.)

To @ZZ whom it may oon/cern.'

Be it known that I, WILLIAM von DAAKE, a citizen of the United States, residing at Van'- couver, in the county of Clarke and State of Washington, have inventednew and useful Improvements in Railway Cattle-Guards, of which the following is a specification.

This invention relates to railway cattleguards for preventing cattle and other stock from passing from one inclosure to another without interfering with the free passage of railwaytrains, and has for its object to provide a cattle-guard of the character referred to which will be strong, durable, inexpensive to manufacture, and simple and eiiicient in operation.

To these ends my invention consists in the features and in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this speciiication wherein- Figure l is a sectional view taken transversely of the railway-rails. Fig. 2 is a detail perspective view of the central section of the cattle-guard, and Fig.`3 is asimilar view of one of the side sections.

In constructing my improved guard I pro-` vide a plurality of rectangular frames,`and inf each of said frames I journala plurality( of parallel rollers arranged in close proximity to one another. The frames are secured tov the railway-ties between the track-rails and on each side thereof in such manner that the rollers lie parallel with the rails, whereby when cattle or other stock attempt to pass over from one inclosureto another across said rollers the latter will turn under the feet of the cattle and cause the cattle to slip, whereby they are unable to securea su flicent foothold to cross the guard.

Each of the frames referred `to comprises two end pieces la and two side pieces 2*. The end pieces each consists of an angle-ironthat is to say, a strip of metal bent into substantially LshapeQ-the vertical anges of the said end pieces being provided with a plurality of perforations a for the reception of the journals of the guard-rollers, while the horizontal anges 5 of said end pieces are provided with screw-holes 6 for the passage rails.

therethrough of screws for attaching the frames to the railway-ties. Each of the side pieces 2b of the 'frames consists of a metallic strip having-itsends bent at right angles to the body of the said side pieces, as atl?. The angular ends 7 of the two side pieces 2" are disposed against the outer faces of the 4end pieces la and are secured thereto by bolts.

Journaled between the end pieces of each of the frames is aseries of rollers each consisting of a metallic tube 9, the opposite ends of which are provided with gudgeons or journals, which are journaled in the perforations 4a of the end pieces, whereby the rollers are free to revolve about their longitudinal axes, and in practice said rollers are so arranged that their peripheries lie in relative close proximity to one another. In putting the guard in place f the sections are laid upon Vthe ties between the railway-rails 13 and on -peach side thereof in such manner that the guard-rollers lie parallel withk the said rails.

'After the frames have been placed in position on the ties they are firmlysecured in place thereonby screws which are screwed through the perforations 6 in the horizontal flanges 5 of the frames and into the rail way-ties. Preferably av fence 14 is erected on each side of the cattle-guard to prevent the cattle or other stock from stoppin g around the y terminations of the fence which sepa- ;vrates one inelosure from another.

As shown, the guard-rollers are arranged vin inclined planes which converge toward the railway- The numeral 1G indicates the central section, which is arranged between the two rails oi' the track and consists of a frame cnstructed in the manner. hereinbefore referred to, the two end pieces la of said frame being .Y

arch-shaped-that is to say, are highest atl the center and inclined downwardly inropp'o 1site directions from the centen toward the ends-and the perforations 4J in which the rollers 9 are journaled are arranged an equal 'distance from the upper edges of said end pieces. The central roller of the frame 16 is therefore the highest, and each succeeding roller on either side of said central roller is slightly lower than said central roller and the rollers as the two rails are approached being disposed lower and lower. The frames of the side sections 17 are made in the man- Ico n ner before described, excepting that the outer side 2fL of each of said outer sections is higher than the opposite inner side 2b, and the end pieces All are inclined or gradually increase in height fromthe inner side pieces 2b to the outer side pieces 2, and the bearings 4a iu which the rollers 9 are journaled are formed equidistant from the upper inclined edges of said inner pieces, whereby the rollers of each side section lie in inclined planes which extend downwardly toward the track-rail, as is most clearly shown in Fig. l of the drawings. It will be seen that the guard-rollers are disposed in inclined planes that converge toward the track-rails, whereby when the cattle attempt to cross said guard their feet are not only caused to slip from under them owing to the rotation of the guard-rolls, but

they are also caused to slipsidewise owing to the inclined position of said rollers. It will be obvious that instead of making each of the central sections in one frame, as shown in Fig. 2, said central section may consist of two side frames arranged between the twov rails of the track, the highest sides of said frames abutting, as shown by the dotted lines in Fig. 1 of the drawings, thus making all of thc frames interchangeable.

ties and twoside pieces rigidly secured to' said end pieces, said frames being arranged longitudinally between the railway-rails and on each side thereof, longitudinal rollers journaled in the end pieces of said frames, the said rollers being disposed in inclined planes converging toward the two railwayrails, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM VON DAAKE.
